QuestionVHD OS - Backup

    I have installed Windows 7 in a VHD. Then I encrypted it using BitLocker. And now I want to backup this VHD, so that I can copy this
    VHD to a different System. There I want to add this VHD to the boot manager and afterwards boot it. It tried that approach, but it does
     work. It will boot the Startup Repair, which can not fix the problem (CorruptBootConfigData).....
    Does anybody know a solution to this problem ?

    Thank you for your help

    I think it's because you encrypted it.  How can you boot from something that was encrypted on a different system, you'd need to decrypt before booting right?

    But the whole point I'm trying to establish is to backup and restore encrpyted systems with just one file to backup...
    I want to have encrypted backups and an effective way to restore them (without first to decrypt and then encrpyt them...)
    I also tried to add a copied VHD to the boot manager on the same system with the same settings that the original vhd has... it also didnt work...

    I think TechNet has the answer:

    http://technet.microsoft.com/en-us/library/dd799282(WS.10).aspx
    "Bitlocker cannot be used to encrypt the host volume containing VHD files used for native VHD boot, and bitlocker cannot be used on volumes contained inside a VHD."

    "Using compressed or encrypted VHDs for native boot. VHDs that have been compressed by NTFS or encrypted using Encrypting File System on the host volume are not supported for native boot. "

    I forgot to mention that: The host volume (which means the real hard disk) ist not encrpyted nor compressed.
    Therefore there cant be the source of the problem... and on the non-backupped VHD ist working fine with activated Bitlocker...
